The Whitney Museum’s current exhibition “Spilling Over Painting Color in the 1960’s” features work from their collection that explore the perception of bold color. Geometry was a powerful vehicle of expression for a number of artists represented.
Alvin Loving’s “Septehedron 34” acrylic on shaped canvas from 1970 presents a 3-D projection of an imaginary seven sided figure on to the 2-D plane. Made up of a lattice of seven right triangles , the viewer is looking directly at one triangular face, surrounded by three other triangles with the three remaining triangles intersecting in the background.
“The Fourth of the Three” from 1963 by Richard Anuszkiewicz has only three colors of paint but the image created appears to have a much more complex palate of various intensities. The undulating grid of not quite all squares was manipulated by varying width of the red lines between the shapes. Using a mathematical plan, the lines are thin at the four sides square panel, then growing thicker, before getting thin again at the center. This creates the optical illusion of movement.
